COD LED - 10W 12cm Strip

Did some experimenting with a 10W COB LED 12cm Strip today. I used a power converter to power it. The LED is rated at 950-1050 lumens at 750mA 12V. The converter I have takes AC to DC 12V 900mA. So I am overdriving the LED some. But I was still surprised that the large computer CPU heatsink I used still gets quite hot after about 20 minutes. The power converter gets even hotter actually. Not sure if that is normal for the converter or not.
The output is really impressive though, I would say its at leas 1000 lumens. I chose a 3000K warm white LED which has a nice color temp to it. It puts out a perfect WIDE flood of light, with absolutely no artifacts.
I will have to play around with more of these LEDs, I love the output, but they do seem to require alot of heatsinking.
Here are the links to the LED and Converter.
